Nature Of Operations [Abstract]
BUSINESS AND ORGANIZATION	BUSINESS AND ORGANIZATION Federal Realty Investment Trust (the “Trust”) is an equity real estate investment trust (“REIT”) specializing in the ownership, management, and redevelopment of retail and mixed-use properties. Our properties are located primarily in communities where we believe retail demand exceeds supply, in strategically selected metropolitan markets in the Mid-Atlantic and Northeast regions of the United States, California, and South Florida. As of September 30, 2021, we owned or had a majority interest in community and neighborhood shopping centers and mixed-use properties which are operated as 106 predominantly retail real estate projects. We operate in a manner intended to enable us to qualify as a REIT for federal income tax purposes. A REIT that distributes at least 90% of its taxable income to its shareholders each year and meets certain other conditions is not taxed on that portion of its taxable income which is distributed to its shareholders. Therefore, federal income taxes on our taxable income have been and are generally expected to be immaterial. We are obligated to pay state taxes, generally consisting of franchise or gross receipts taxes in certain states. Such state taxes also have not been material.

Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of presentation The accompanying consolidated balance sheet as of December 31, 2020, which has been derived from audited financial statements, and unaudited interim consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission. Certain information and note disclosures normally included in annual financial statements prepared in accordance with accounting principles generally accepted in the United States (GAAP) have been omitted pursuant to those rules and regulations, although we believe that the disclosures made are adequate to make the information not misleading. It is suggested that these financial statements be read in conjunction with the financial statements and notes thereto included in our latest Annual Report on Form 10-K. In the opinion of management, all adjustments (consisting of normal, recurring adjustments) necessary for a fair presentation for the periods presented have been included. The results of operations for the three and nine months ended September 30, 2021 are not necessarily indicative of the results that may be expected for the full year. Principles of Consolidation Our consolidated financial statements include the accounts of the Trust, its corporate subsidiaries, and all entities in which the Trust has a controlling interest or has been determined to be the primary beneficiary of a variable interest entity (“VIE”). The equity interests of other investors are reflected as noncontrolling interests or redeemable noncontrolling interests. All significant intercompany transactions and balances are eliminated in consolidation. We account for our interests in joint ventures, which we do not control, using the equity method of accounting. Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America, referred to as “GAAP,” requires management to make estimates and assumptions that in certain circumstances affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities, and revenues and expenses. These estimates are prepared using management’s best judgment, after considering past, current and expected events and economic conditions. Actual results could differ from these estimates. Impacts of COVID-19 Pandemic Since March 2020, we have been, and continue to be, impacted by the novel coronavirus ("COVID-19") pandemic. While we currently expect the impact to our properties to be temporary in nature, the extent of the future effects of COVID-19 on our business, results of operations, cash flows, and growth prospects is highly uncertain and will ultimately depend on future developments, none of which can be predicted with any certainty. Federal, state, and local governments have taken various actions since the onset of the pandemic to mitigate the spread of COVID-19. These actions included the closure of nonessential businesses and ordering residents to generally stay at home at the onset of the pandemic, phased re-openings and capacity limitations, and now generally lifted restrictions. While the overall economy is showing signs of recovery from the initial impacts of COVID-19, workforce shortages, global supply chain bottlenecks and shortages, inflation, as well as COVID-19 variants are impacting the pace of recovery. Closures and restrictions, along with general concern over the spread of COVID-19, required a significant number of tenants to close their operations or to significantly limit the amount of business they were able to conduct, which impacted their ability to timely pay rent as required under our leases and also caused many tenants to close their businesses permanently. With the re-openings, our results have improved during the first nine months of 2021 and collectibility related impacts have continued to decrease. During the three and nine months ended September 30, 2021, we recognized collectibility related adjustments of $0.6 million and $21.8 million, respectively, as compared to $29.4 million and $87.6 million for the three and nine months ended September 30, 2020, respectively. This includes not only the impact of tenants recognized on a cash basis but also changes in our collectibility assessments from probable to not probable, disputed rents, and any rent abatements directly related to COVID-19. As of September 30, 2021, the revenue from approximately 35% of our tenants (based on total commercial leases) is being recognized on a cash basis. For more information, see Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations - Outlook. Mortgage Notes Receivable On May 11, 2021, two of our outstanding mortgage notes receivable were repaid. Including interest, the net proceeds were $33.8 million. As a result of the transaction, our mortgage notes receivable, net of valuation allowance, decreased $30.3 million. Forward Equity Sales On February 24, 2021, we replaced our existing at-the-market (“ATM”) equity program with a new ATM equity program in which we may from time to time offer and sell common shares having an aggregate offering price of up to $500.0 million. The new ATM equity program also allows shares to be sold through forward sales contracts. Our forward sales contracts currently meet all the conditions for equity classification; and therefore, we record common stock on the settlement date at the purchase price contemplated by the contract. Furthermore, we consider the potential dilution resulting from forward sales contracts in our earnings per share calculations. We use the treasury method to determine the dilution, if any, from the forward sales contracts during the period of time prior to settlement. As of September 30, 2021, no forward sales contracts have settled.

Under the amended guidance, lessors will classify a lease with variable payments that do not depend on an index or rate as an operating lease if the lease would have been classified as a sales-type lease or a direct financing lease under the previous ASU 842 classification criteria, and sales-type or direct financing lease classification would result in a Day 1 loss. This guidance is effective for annual periods beginning after December 15, 2021, and interim periods therein.

Real Estate [Abstract]
Real Estate Disclosure	On January 4, 2021, we acquired our partner's 20% interest in our joint venture arrangement related to the Pike & Rose hotel for $2.3 million, and repaid the $31.5 million mortgage loan encumbering the hotel. As a result of the transaction, we gained control of the hotel, and effective January 4, 2021, we have consolidated this asset. We also recognized a gain on acquisition of the controlling interest of $2.1 million related to the difference between the carrying value and fair value of the previously held equity interest. On February 22, 2021, we acquired the fee interest at our Mount Vernon Plaza property in Alexandria, Virginia for $5.6 million. As a result of this transaction, the "operating lease right of use assets" and "operating lease liabilities" on our consolidated balance sheet decreased by $9.8 million. We now own the entire fee interest on this property. Property Acquisitions During the nine months ended September 30, 2021, we acquired the following properties: Date Acquired Property City/State Gross Leasable Area (GLA) Ownership % Gross Value (in square feet) (in millions) April 30, 2021 Chesterbrook (1) McLean, Virginia 90,000 80 % $ 32.1 (2) June 1, 2021 Grossmont Center (1) La Mesa, California 933,000 60 % $ 175.0 (3) June 14, 2021 Camelback Colonnade (1) Phoenix, Arizona 642,000 98 % $ 162.5 (4) June 14, 2021 Hilton Village (1) Scottsdale, Arizona 93,000 98 % $ 37.5 (5) September 2, 2021 Twinbrooke Shopping Centre Fairfax, Virginia 109,000 100 % $ 33.8 (6) (1) These acquisitions were completed through newly formed joint ventures, for which we own the controlling interest listed above, and therefore, these properties are consolidated in our financial statements.

On April 16, 2021, we repaid $100.0 million of our existing $400.0 million term loan, amended the agreement on the remaining $300.0 million to lower the current spread over LIBOR from 135 basis points to 80 basis points based on our current credit rating, and extended the initial maturity date to April 16, 2024, along with two one-year extensions, at our option. On September 1, 2021, we repaid the $7.9 million mortgage loan on Plaza Del Sol, at par, prior to its original maturity date. During the three and nine months ended September 30, 2021, there were no borrowings on our $1.0 billion revolving credit facility. Our revolving credit facility, term loan, and certain notes require us to comply with various financial covenants, including the maintenance of minimum shareholders' equity and debt coverage ratios and a maximum ratio of debt to net worth. As of September 30, 2021, we were in compliance with all default related debt covenants.

Fair Value Disclosures [Abstract]
FAIR VALUE OF FINANCIAL INSTRUMENTS	FAIR VALUE OF FINANCIAL INSTRUMENTS Except as disclosed below, the carrying amount of our financial instruments approximates their fair value. The fair value of our mortgages payable, notes payable and senior notes and debentures is sensitive to fluctuations in interest rates. Quoted market prices (Level 1) were used to estimate the fair value of our marketable senior notes and debentures and discounted cash flow analysis (Level 2) is generally used to estimate the fair value of our mortgages and notes payable. Considerable judgment is necessary to estimate the fair value of financial instruments. The estimates of fair value presented herein are not necessarily indicative of the amounts that could be realized upon disposition of the financial instruments. A summary of the carrying amount and fair value of our mortgages payable, notes payable and senior notes and debentures is as follows: September 30, 2021 December 31, 2020 Carrying Fair Value Carrying Fair Value (In thousands) Mortgages and notes payable $ 758,665 $ 773,188 $ 886,887 $ 879,390 Senior notes and debentures $ 3,405,685 $ 3,725,056 $ 3,404,488 $ 3,761,465 As of September 30, 2021, we have two interest rate swap agreements with notional amounts of $56.5 million that are measured at fair value on a recurring basis. The interest rate swap agreements fix the interest rate on $56.5 million of mortgage payables at 3.67% through December 15, 2029. The fair values of the interest rate swap agreements are based on the estimated amounts we would receive or pay to terminate the contracts at the reporting date and are determined using interest rate pricing models and interest rate related observable inputs. The fair value of our swaps at September 30, 2021 was a liability of $2.0 million and is included in "other liabilities and deferred credits" on our consolidated balance sheet. For the three and nine months ended September 30, 2021, the value of our interest rate swaps increased $0.4 million and $2.7 million, respectively (including $0.2 million reclassified from other comprehensive income to interest expense for the three months, and $0.7 million reclassified from other comprehensive income to interest expense for the nine months ended September 30, 2021).

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES We are sometimes involved in lawsuits, warranty claims, and environmental matters arising in the ordinary course of business. Management makes assumptions and estimates concerning the likelihood and amount of any potential loss relating to these matters. We are currently a party to various legal proceedings. We accrue a liability for litigation if an unfavorable outcome is probable and the amount of loss can be reasonably estimated. If an unfavorable outcome is probable and a reasonable estimate of the loss is a range, we accrue the best estimate within the range; however, if no amount within the range is a better estimate than any other amount, the minimum within the range is accrued. Legal fees related to litigation are expensed as incurred. We do not believe that the ultimate outcome of these matters, either individually or in the aggregate, could have a material adverse effect on our financial position or overall trends in results of operations; however, litigation is subject to inherent uncertainties. Also under our leases, tenants are typically obligated to indemnify us from and against all liabilities, costs and expenses imposed upon or asserted against us (1) as owner of the properties due to certain matters relating to the operation of the properties by the tenant, and (2) where appropriate, due to certain matters relating to the ownership of the properties prior to their acquisition by us. Under the terms of certain partnership agreements, the partners have the right to exchange their operating partnership units for cash or common shares, at our option. A total of 694,133 downREIT operating partnership units are outstanding which have a total fair value of approximately $81.9 million, which is calculated by multiplying the outstanding number of downREIT partnership units by our closing stock price on September 30, 2021.

Earnings Per Share [Abstract]
EARNINGS PER SHARE	EARNINGS PER SHARE We have calculated earnings per share (“EPS”) under the two-class method. The two-class method is an earnings allocation methodology whereby EPS for each class of common stock and participating securities is calculated according to dividends declared and participation rights in undistributed earnings. For the three and nine months ended September 30, 2021, we had 0.3 million and for the three and nine months ended September 30, 2020, we had 0.2 million weighted average unvested shares outstanding, respectively, which are considered participating securities. Therefore, we have allocated our earnings for basic and diluted EPS between common shares and unvested shares; the portion of earnings allocated to the unvested shares is reflected as “earnings allocated to unvested shares” in the reconciliation below. The following potentially issuable shares were excluded from the diluted EPS calculation because their impact is anti-dilutive: • exercise of 682 stock options for both the three and nine months ended September 30, 2021 and 2020, • conversions of downREIT operating partnership units and 5.417% Series 1 Cumulative Convertible Preferred Shares for both the three and nine months ended September 30, 2021 and 2020, and • the issuance of 0.9 million and 1.7 million shares issuable under forward sales agreements for the three and nine months ended September 30, 2021, respectively. Additionally, 10,441 unvested restricted stock units are excluded from the diluted EPS calculation as the market based performance criteria in the awards has not yet been achieved.

Accounting Policies [Abstract]
Basis of Presentation	Basis of presentation The accompanying consolidated balance sheet as of December 31, 2020, which has been derived from audited financial statements, and unaudited interim consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission. Certain information and note disclosures normally included in annual financial statements prepared in accordance with accounting principles generally accepted in the United States (GAAP) have been omitted pursuant to those rules and regulations, although we believe that the disclosures made are adequate to make the information not misleading. It is suggested that these financial statements be read in conjunction with the financial statements and notes thereto included in our latest Annual Report on Form 10-K. In the opinion of management, all adjustments (consisting of normal, recurring adjustments) necessary for a fair presentation for the periods presented have been included. The results of operations for the three and nine months ended September 30, 2021 are not necessarily indicative of the results that may be expected for the full year.
Principles of Consolidation	Principles of Consolidation Our consolidated financial statements include the accounts of the Trust, its corporate subsidiaries, and all entities in which the Trust has a controlling interest or has been determined to be the primary beneficiary of a variable interest entity (“VIE”). The equity interests of other investors are reflected as noncontrolling interests or redeemable noncontrolling interests. All significant intercompany transactions and balances are eliminated in consolidation. We account for our interests in joint ventures, which we do not control, using the equity method of accounting.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America, referred to as “GAAP,” requires management to make estimates and assumptions that in certain circumstances affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities, and revenues and expenses. These estimates are prepared using management’s best judgment, after considering past, current and expected events and economic conditions. Actual results could differ from these estimates.
Forward Equity Sales	Forward Equity SalesOn February 24, 2021, we replaced our existing at-the-market (“ATM”) equity program with a new ATM equity program in which we may from time to time offer and sell common shares having an aggregate offering price of up to $500.0 million. The new ATM equity program also allows shares to be sold through forward sales contracts. Our forward sales contracts currently meet all the conditions for equity classification; and therefore, we record common stock on the settlement date at the purchase price contemplated by the contract. Furthermore, we consider the potential dilution resulting from forward sales contracts in our earnings per share calculations. We use the treasury method to determine the dilution, if any, from the forward sales contracts during the period of time prior to settlement. As of September 30, 2021, no forward sales contracts have settled.
